"nation, with a work-lsupport, oi an arm glancing blow instead ofadirect blow, and the hand is swept out from under the drop in e mannernot liable to injure the hand. As the stock or Work upon which the drop6 op erates Varies in thickness and/becomes more or less buckled Whenstruck by said drop, it is necessary to provide more or less space l:tween the lower edge of the .i'ree end portion 12 of the arm 11 and theface of the die. in order to prevent the fingers oi the operator fromheing caught in this space between the arm 11 and the face of the die 3,the fixed end portion 13 of the arm 11 is constructed to extend helowthe face or top oi the di 3 and so as to st ilre the hand in advance oithe end portion 12 and sweep the lingers oli' oi the die and from underthe drop.

I do not Wish to limit myself to the exact construction shown anddeserilied, as changes may he made in the details oi constructionWithout departing ironi the spirit and scope of the invention.

What I claim my invention and desire 1. In a press or similar device,the conilai- 1 adapted to reciprocate across said \n'u-k-support, saidarm being provided with apro ecsupport, substantially described.

2. In apress or similar device, the eonihi- I nation with ework-support, of an arm a-dap ted to reciprocate across saidWork-support, the fixed end of said arm heing at an {angle with theplane of movement or the arm and prmided with e projection extendingllGlOW the top of the Work-support, s'uhstentiall :m deserilzed.
